Synthetic Route of 61-82-5, New Advances in Chemical Research in 2021. Redox catalysis has been broadly utilized in electrochemical synthesis due to its kinetic advantages over direct electrolysis. 61-82-5, name is 1H-1,2,4-Triazol-5-amine, molecular formula is C2H4N4, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, below Introduce a new synthetic route.
General procedure: A mixture of aldehyde (1.0 mmol), dimedone (1.0 mmol),1H-1,2,4-triazol-3-amine (1.0 mmol) and nano-AlPO4(SO3H) (0.1 g) was stirred in the acetonitrile (4.0 mL)at 50 C for an appropriate time. After the completion of thereaction as indicated by TLC, dichloromethane was addedto the solidified mixture and the insoluble catalyst was separatedby centrifugation. Evaporation of the solvent from thefiltrate and recrystallization of the solid residue from hot ethanolafforded the pure products in good to excellent yields
In the meantime we’ve collected together some recent articles in this area about 61-82-5 to whet your appetite. Happy reading!
